The Milwaukee Digital Refractometer is a revelation for the modern fishkeeper for testing aquarium salinity/specific gravity and has been met with excellent reviews.
Say goodbye to squinting through an out of focus refractometer whilst awkwardly trying to calibrate it!
Milwaukee Digital Refractometer for Seawater Measurement
The MA887 is an optical instrument. It employs the measurement of the refractive index to determine the salinity of natural and artificial seawater, ocean water or brackish water. The digital refractometer eliminates the uncertainty associated with mechanical refractometers. It is easily portable for ship, shore or home use.
Milwaukee Digital Refractometer Calibration
The MA887 refractometer is an optical device that is simple and quick to use. Samples are measured after a simple user calibration with distilled or deionized water (RO). All you have to do is put a small sample of RO on testing window and press zero. Dry the are and add your salt water sample then press read. Within seconds, the refractive index and temperature are measured and converted into one of three popular measurement units; Practical Salinity Units (PSU), Salinity in parts per thousand (ppt), or Specific Gravity (S.G. (20/20). All conversion algorithms are based upon respected scientific publications using the physical properties of seawater (not sodium chloride). The temperature (in °C or °F) is also displayed on the large dual level display along with helpful message codes.
Key features include:
Automatic Temperature Compensation (ATC)
Battery operation with Low Power indicator
Automatically turns off after 3 minutes of non-use.
Stainless Steel Sample Well and Prism
Place a few drops of the sample in the well and press the READ key.
